Blackmer Pumps

Blackmer

Blackmer was incorporated in 1903 and is the leading manufacturer of positive displacement pumps, centrifugal pumps and compressors for the transfer of liquid and gas products worldwide. Positive displacement pump technologies include sliding vane, eccentric disc and peristaltic hose.

The sliding-vane pump and centrifugal pump lines are characterised by proven life-cycle cost features. The compressor technologies include reciprocating, rotary vane, and screw.

Through a global network of distributors and original equipment manufacturers� base channels, Blackmer serves the following markets: refined fuels, pulp and paper, oilfield, wastewater, food/sanitary, military/marine, transport and chemical process.

Blackmer – Pumps

Sliding-vane pumps: These pumps have a number of vanes that are free to slide into or out of slots in the pump rotor. When the pump driver turns the rotor, centrifugal force, rods, and/or pressurised fluid cause the vanes to move outward in their slots and bear against the inner bore of the pump casing, forming pumping chambers. As the rotor revolves, fluid flows into the area between the vanes (pumping chambers) when they pass the suction port. This fluid is transported around the pump casing until the discharge port is reached. At this point the fluid is squeezed out into the discharge piping.

Eccentric-movement pumps: These pumps consist of a cylinder and a pumping element mounted on an eccentric shaft. As the eccentric shaft is rotated, the pumping element forms chambers within the cylinder, which increase in size at the intake port, drawing fluid into the pumping chamber. The fluid is transported to the discharge port, where the pumping chamber size is decreased. This action squeezes the fluid out into the discharge piping.
